Comment 16: Public stormwater facilities shall be designed so permanent long-term <br /> irrigation systems are not needed. What about private stormwater management facilities? <br /> Finding: Methods of irrigation for private facilities is up to the applicant. Plantings are an <br /> essential element for many of the various treatment systems. The applicant will be required to <br /> maintain the vegetative aspects of the facilities. Failure to properly maintain the facilities will be <br /> considered a public nuisance and enforcement policies are established in Chapter 6 of the Eugene <br /> code. Inquiry and response only. <br /> Comment 17: Shut off valves are required to protect the city sewer systems or onsite <br /> infiltration facilities. What would these facilities be in the River Road/Santa Clara? <br /> Finding: Shut off valves are required at fuel dispensing facilities and are intended to protect <br /> <br /> both the wastewater and stormwater systems depending on where a contamination spill may occur. <br /> The covered area over the fuel dispensing area drains to the city wastewater system or an approved <br /> <br /> pretreatment facility. A shut off valve is required to be installed before the domestic wastewater tie- <br /> in. This valve remains closed and only opened to allow incidental drainage. The uncovered areas <br /> surrounding the fueling pads drain to an approved pollution reduction facility before discharging to <br /> an approved destination stormwater facility. A shut off valve is required before the approved <br /> discharge point. The valves remain open to facilitate stormwater flows and shall be immediately <br /> closed in the event of a spill. The Manual was edited to clarify this intent. <br /> Comment 18: Liquid materials shall be stored and contained in such a manner that if <br /> the container(s) is ruptured, the contents will not discharge, flow, or be washed into the a <br /> receiving system. Could the "drainage system" include drywells? <br /> Finding: Yes. Inquiry and response only. <br /> Comment 19: Is pavement for all the solid waste storage areas, containers, and trash <br /> compactors (specifically the multi-residential) going to add unnecessary impervious surfaces to <br /> the River Road/Santa Clara Basin? <br /> Finding: No. To best serve water quality goals there are cases where pervious pavements are <br /> not appropriate. Impervious pavement is used in areas where solid waste, etc., is stored to keep <br /> containments that spill or leach from the contained material from infiltrating into the soil. Inquiry <br /> and response only. <br /> Comment 20: Can the paved waste storage area required under a structural cover or <br /> trash compactor be paved using pervious pavers? Can the paved material transfer areas <br /> required under and around loading and unloading areas be paved using pervious pavers? Can <br /> wash pads under and around washing activities be pervious pavement? <br /> Finding: No. See findings for comment 19. <br /> Administrative Order - 6 <br /> <br />
